Document Summary
Interaction effects: occurs when the effect of one iv depends on the level of another. Remember: factorial design means there is more than one iv involved. **short answer for test 2:look at a matrix and come up with the corresponding graph; or a graph and come up with corresponding matrix. Ceiling effect- this occurs when scores on 2 or more conditions are near the maximum, it can give the impression that no differences exist between conditions. Floor effect (a group cannot get any lower) (i. e. the first group regarding behaviour may not be able to possibly get any lower than zero after a treatment, so can be misinterpreted) Axbxc *most important to publish because it shows an overall reaction. **will not be tested on any statistics on test** Completely between-subject design: all aspects tested are between subjects, same number of subjects per every group as well.
